This article addresses the protest against the 2019 Nobel Prize in Literature to Peter Handke as an example of transnational memory activism. It analyzes from a transnational mobilization perspective how activists achieved a globally visible protest in Stockholm and what role memory played in the protest mobilization and framing. Genocide survivors and former refugees, human rights activists, journalists, and academics formed a transnational protest coalition. In this way, they drew international attention to their outrage at the honoring of an author who is criticized for denying the Bosnian genocide. The analysis shows that memories of the violent dissolution of Yugoslavia and genocide united the diverse protesters as a “memory community” and shaped their framing. The protesters warned of the potential repercussions of the Nobel Prize to Handke for the internationalization and normalization of genocide denial. They argued that locally, Serb nationalist politicians can find legitimation in it for divisive politics. Moreover, they put the prize in a larger context of globally rising right extremism and islamophobia that find inspiration in the very Serb nationalist ideology and its propagators of the 1990s conflict.
